Deprecation Notices
-------------------
-* Significant ABI changes are planned for struct rte_eth_dev to support up to
- 1024 queues per port. This change will be in release 2.2.
- There is no backward compatibility planned from release 2.2.
- All binaries will need to be rebuilt from release 2.2.
-
-* ABI changes are planned for struct rte_intr_handle, struct rte_eth_conf
- and struct eth_dev_ops to support interrupt mode feature from release 2.1.
- Those changes may be enabled in the release 2.1 with CONFIG_RTE_NEXT_ABI.
-
-* The EAL function rte_eal_pci_close_one is deprecated because renamed to
- rte_eal_pci_detach.
-
-* The Macros RTE_HASH_BUCKET_ENTRIES_MAX and RTE_HASH_KEY_LENGTH_MAX are
- deprecated and will be removed with version 2.2.
-
-* Significant ABI changes are planned for struct rte_mbuf, struct rte_kni_mbuf,
- and several ``PKT_RX_`` flags will be removed, to support unified packet type
- from release 2.1. Those changes may be enabled in the upcoming release 2.1
- with CONFIG_RTE_NEXT_ABI.
-
-* librte_malloc library has been integrated into librte_eal. The 2.1 release
- creates a dummy/empty malloc library to fulfill binaries with dynamic linking
- dependencies on librte_malloc.so. Such dummy library will not be created from
- release 2.2 so binaries will need to be rebuilt.
-
* The following fields have been deprecated in rte_eth_stats:
- imissed, ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
+ ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
-* API for flow director filters has been replaced by rte_eth_dev_filter_ctrl.
- Following old API is deprecated and will be removed with version 2.2 without
- backward compatibility.
- Functions: rte_eth_dev_fdir_*.
- Structures: rte_fdir_*, rte_eth_fdir.
- Enums: rte_l4type, rte_iptype.
-
* ABI changes are planned for struct rte_eth_fdir_flow_ext in order to support
flow director filtering in VF. The release 2.1 does not contain these ABI
changes, but release 2.2 will, and no backwards compatibility is planned.
-* ABI change is planned to extend the SCTP flow's key input from release 2.1.
- The change may be enabled in the release 2.1 with CONFIG_RTE_NEXT_ABI.
+* ABI changes are planned for struct rte_eth_fdir_filter and
+ rte_eth_fdir_masks in order to support new flow director modes,
+ MAC VLAN and Cloud, on x550. The MAC VLAN mode means the MAC and
+ VLAN are monitored. The Cloud mode is for VxLAN and NVGRE, and
+ the tunnel type, TNI/VNI, inner MAC and inner VLAN are monitored.
+ The release 2.2 will contain these changes without backwards compatibility.
+
+* ABI changes are planned for struct virtio_net in order to support vhost-user
+ multiple queues feature.
+ It should be integrated in release 2.2 without backward compatibility.
+
+* The scheduler hierarchy structure (rte_sched_port_hierarchy) will change to
+ allow for a larger number of subport entries.
+ The number of available traffic_classes and queues may also change.
+ The mbuf structure element for sched hierarchy will also change from a single
+ 32 bit to a 64 bit structure.
+
+* The scheduler statistics structure will change to allow keeping track of
+ RED actions.
+
+* librte_table: New functions for table entry bulk add/delete will be added
+ to the table operations structure.
+
+* librte_table hash: Key mask parameter will be added to the hash table
+ parameter structure for 8-byte key and 16-byte key extendible bucket and
+ LRU tables.
+
+* librte_pipeline: The prototype for the pipeline input port, output port
+ and table action handlers will be updated:
+ the pipeline parameter will be added, the packets mask parameter will be
+ either removed (for input port action handler) or made input-only.
